As Israeli threats of war against Iran encounter stiff opposition in the US, the new administration mulls over imposing sanctions on Tel Aviv.

US President Barack Obama and Secretary of State Hillary Clinton are mulling over a plan to impose sanctions against Israel if the right-wing government of Benjamin Netanyahu implements its long-sought policy of countering Iran's nuclear activities by taking military action against the country.

According to a report by RIA Novosti, the Obama White House is on a collision course with longstanding Israeli plans to launch a military strike on Iranian nuclear infrastructure.

Washington favors diplomatic measures -- at least for as long as the Obama administration believes there is room for the pursuit of its plans to engage Iran "diplomatically" over its nuclear case.

President Obama has been making efforts to put his belief into practice that America should talk to its adversaries such as Iran, Syria, North Korea and Venezuela.

However, since hawkish Prime Minister Netanyahu took office Israel has been buzzing with rumors of a possible military strike on Iran's nuclear sites if the United States fails to achieve progress in talks with Iran.

Earlier on Wednesday Israel's Home Front Command announced plans to mobilize the Israeli army as well as the public to hold the largest military exercise in its history on June 2.

The head of Israel's Department for Population at the Home Front Command Colonel Hilik Sofer said by holding the weeklong military exercise Israel seeks to "transform the population from a passive to an active one... We want the citizens to understand that war can happen tomorrow morning."

Earlier in March, hawkish Israeli Prime Minister Netanyahu raised the alarm about a major military conflict in the upcoming months.

According to Debka, which is believed to be closely connected with the Israeli spy agency Mossad, "His main consideration is that Israel expects to be embroiled in a major military confrontation in the next few months with Iran, Hamas or Hezbollah -- or all three at once."
